Justin Timberlake throws Jessica Biel a pajama party for her 38th birthday

Jessica Biel's next trip around the sun is off to a very good start, thanks to her husband, Justin Timberlake.

"Celebrating my birthday in style... and by that I mean, in pajamas. I made Justin PROMISE not to sing Happy Birthday to me, so he improvised. Sorry you can't hear it, but I'm still laughing," Biel wrote in an Instagram post on Tuesday.

"Thank you, you wonderful human, for really listening to me, and for throwing my kinda party. And thank YOU ALL for the birthday wishes. Feeling the love," she added.

Biel shared three sweet photos from her pajama party. In one snap, a tie-dye-clad Timberlake, 39, is shown hugging the actress from behind.

"I LOVE YOU!!!" Timberlake replied in a comment. "Happy Bday, you beautiful, loving, caring, wonderful 🦊 of a mom and wife!!!"

Biel, who shares 4-year-old son, Silas, with Timberlake, woke up on Tuesday to doughnuts, bacon and scrambled eggs plated in the shape of a smiling face.

"My boys know me SO well," the "7th Heaven" alum gushed in her Instagram story. "Just came downstairs to this perfect birthday breakfast."

Last month, Timberlake and his wife of seven years both posted sentimental Valentine's Day tributes. Timberlake shared a throwback picture from their early courtship days.

"It ain't hard to tell from my face!!! When you know, you know," he wrote. "I love you, my funny Valentine. Every day the 14th!!! Happy Love Day, y'all!!"

The actress and singer first started dating in 2007 and married in 2012. In an interview with Marie Claire in 2017, Biel said she and her husband work well together because "We have similar values; we believe in loyalty, honesty. We like to have fun. We like a lot of the same things."
